My new app Draw Lights is now out for the iPhone and iPod Touch. It's a Christmas-lights drawing app; take a photo, use an existing photo, or use one of the holiday-themed background images provided, then use your finger to draw lights on the image. There are 30 different lights to choose from, including mini lights, stars, snowflakes, and luminarias.
I also created this Santa Hand icon as a custom pointer icon for the demo video I did. You're welcome to use it in your own projects. I've also submitted it to Michael Glasser's Screenflow custom icons page; it should show up there soon.
